Bag dust collectors in cement plants are the main pollution control equipment in the cement industry. The safe and efficient operation of dust removal systems is very important. The bag filter is a dry dust filter. Of course, bag filters in cement plants should be as close as possible to pollution sources. Vacuum cleaners placed in the open air should be equipped with rain protection measures.
The main structure of the baghouse in the cement plant is composed of an upper box, a middle box, a lower box (ash hopper), a ash cleaning system, and an ash discharge mechanism. The performance of bag filters in cement plants is good. In addition to the correct selection of filter bag materials, the dust removal system plays a decisive role in bag filters. Therefore, the method of dust removal is one of the characteristics of bag filters in cement plants. An important part of the operation of bag filters in cement plants.
The bag filter control box shall have a single circuit power supply. In addition to the usual ash cleaning, ash unloading and transportation functions, the control box of the bag filter should also have upper and lower temperature alarms and their handling measures, anti-condensation and adhesion control of the ash bucket, and anti-combustion and explosion control of pulverized coal. Measures, depending on the intended use of the equipment. The working environment temperature of the control box should meet the requirements of the instructions. For control boxes used in high altitude areas, the type selection of main components must be one level higher than that of conventional control boxes. For control boxes used in high humidity areas, moisture and corrosion resistant components must be selected.
According to the nature and process conditions of the dust-containing gas and dust being processed, select the type of bag filter and the type of filter material, and determine the appropriate filtering wind speed according to the process conditions, such as the dust concentration at the entrance. When the entrance When the dust concentration is low, a higher wind speed is used. The processing air volume of the bag type dust collector should be 1% of the amount of gas that the production equipment needs to process. 1 times the calculation. If the air volume fluctuates greatly, a larger value should be taken. If the kiln, mill and cooler equipment selects multiple boxes of off-line ash bag dust collectors, the number of boxes should be six or more. For the treatment of high-temperature, high-humidity, flammable and explosive dust-containing gas, filter materials with high temperature resistance, anti-condensation and anti-static properties should be selected respectively. Membrane filter materials should be selected to handle dust-containing gas with a dust concentration of more than 500 g / m3.
